Verity's KeyView Pro doesn't have any WordStar specific file import filters, but can read WordStar for DOS 3.x and 4.0 files as these are relatively simple text formats. These can then be saved in Rich text Format (RTF). KeyView Pro offers a batch conversion facility. A demo of the program used to be available from Verity now appears to be HP Autonomy, and the KeyView program isn't available for free download.
